Just found sys.excepthook. I see that there is no sys.exit() call in its documented behavior: https://docs.python.org/2/library/sys.html


sys.excepthook(type, value, traceback)
This function prints out a given traceback and exception to sys.stderr.

When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook.
